My bad.

I've only looked at the difference of the dev_id for the 2 functions,
not at the usage of it with the function registered by 'request_irq'.
This one is obviously correct, or the driver would have some problems
somewhere.
I don't know why have chosen to change request_irq and not free_irq.

So obvious. I'm a little embarrassed and will send a v2.

Thx for the quick reply and review.


All the 3 patches being in "/drivers/scsi/arm/", do you prefer only 1
patch for the 3, or separated as I've done so far?
